Wavelength converting light-emitting devices and methods of making the same are provided. In some embodiments, the devices include a phosphor material region designed to convert the wavelength of emitted light.

Wavelength converting light-emitting devices and methods of making the same

The present invention relates to light-emitting diodes (LEDs), and related components, processes, systems, and methods. In certain embodiments, an LED that provides improved optical and thermal efficiency when used in optical systems with a non-rectangular input aperture (e.g., a circular aperture) is described. In some embodiments, the emission surface of the LED and/or an emitter output aperture can be shaped (e.g., in a non-rectangular shape) such that enhanced optical and thermal efficiencies are achieved. In addition, in some embodiments, chip designs and processes that may be employed in order to produce such devices are described.

Light-emitting diode architectures for enhanced performance

A slim LED package configured to handle large current, having a narrow width, an LED chip mounting area positioned centro-symmetrically within the package, mounting holes positioned equidistantly from the mounting area, wherein multiple packages may be arranged with alternating anode and cathode ends in such a manner that a high-power density radiometric flux line may be created. Some embodiments include current density management areas positioned on one more sides of the LED chip mounting area.

Packaging method and system for LEDs

Light-emitting devices are described herein. Some embodiments relate to light-emitting diodes with light-emitting sections that are independently electrically addressable. The devices may be used in a variety of applications including illumination and general lighting.

Light-emitting device including independently electrically addressable sections

Illumination assemblies, components, and related methods are described. An illumination assembly can include at least one solid state light-emitting device, and at least one light guide including a light homogenization region configured to receive light emitted by the solid state light-emitting device and including a light output boundary. The light homogenization region substantially uniformly distributes light outputted over the light output boundary. A wavelength converting material can be disposed within at least a portion of the light homogenization region. In some assemblies, a light extraction region can be configured to receive light from the light output boundary of the light homogenization region, and can have a length along which received light propagates and an emission surface through which light is emitted. The light extraction region can include a wavelength converting material disposed within at least a portion of the light extraction region.

Illumination assembly including wavelength converting material

Illumination assemblies, components, and related methods are described. An illumination assembly can include at least one solid state light-emitting device, an emission surface through which light is emitted, and a wavelength converting material that wavelength converts at least some light emitted by the solid state light-emitting device. The wavelength converting material can have a first density per unit area of the emission surface at a first location and a second density per unit area of the emission surface at a second location, wherein the second density is substantially different from the first density, and wherein the density per unit area is defined with a 1&#xd7;1 cmaveraging area. Another illumination assembly can include a light guide configured to receive light emitted by a solid state light-emitting device. The light guide can have a length along which received light propagates and an emission surface substantially parallel to the length of the light guide and through which light is emitted. A wavelength converting material can have a density per unit area of the emission surface that substantially increases along the length of the light guide.

Illumination assembly including wavelength converting material having spatially varying density

Light-emitting structures, and related components, systems, and methods associated therewith are provided. In one embodiment, a light-emitting structure includes at least one LED, a contact bond pad supported by the at least one LED, and a flexible circuit member bonded to the contact bond pad.

Flexible circuit light-emitting structures

Methods of forming light-emitting structures, as well as related devices and/or systems are described. In some cases, the methods utilize a layer transfer and/or layer separation step(s) used to form such structures.

Methods of forming light-emitting structures

Light emitting devices, and related components, processes, systems and methods are disclosed.

Light-emitting devices for liquid crystal displays

Light-emitting devices (e.g., LEDs) and methods associated with such devices are provided. In some embodiments, the device includes a distribution of light-generating portions (including active regions) that are spatially localized and separated (e.g., horizontally or vertically) from one or more patterned light extraction portions. This arrangement can allow light generated by the device to propagate and pass through regions of low absorption (e.g., light-extraction portions) rather than in regions of high absorption (e.g., light-generating portions), which can enhance light emission.

Spatial localization of light-generating portions in LEDs

Light-emitting devices can include a package that supports one or more light-emitting die (e.g., light-emitting diode die, laser diode die) and which can ensure mechanically stability, can facilitate electrical and/or thermal coupling with light-emitting die, and can manipulate the manner by which light generated by the die is emitted out of the light-emitting device. The package can also facilitate the integration of the light-emitting devices in various components and systems. For example, suitable packages may facilitate the use of light-emitting devices in components and systems such as light-emitting panel assemblies, LCD back lighting, general lighting, decorative or display lighting, automotive lighting, and other types of lighting components and systems.

Light-emitting devices and related systems

Illumination systems, which include at least one light source (e.g., LED and/or laser diode), light sensor, and a power source are described. In certain embodiments, a light sensor and a microprocessor are used to detect light emitted by a light source and to adjust the power signal provided to the light source at least partially based on the detected light. Some embodiments may enable the color point and/or brightness of the emitted light to be controlled at least partially based on the detected light. The illumination systems may be designed to be used as a liquid crystal display (LCD), general lighting apparatus, or any other illumination device.

LED color management and display systems

Light-emitting devices, and related components, processes, systems and methods are disclosed.

Light emitting devices for liquid crystal displays

Devices, such as light-emitting devices (e.g., LEDs), and methods associated with such devices are provided. A light-emitting device may include an interface through which emitted light passes therethrough. The interface having a dielectric function that varies spatially according to a pattern, wherein the pattern is arranged to provide light emission that has a substantially isotropic emission pattern and is more collimated than a Lambertian distribution of light.
